re: Ways to keep house cool while waiting to repair AC situation.

Upstairs has 4 bedrooms, the upstairs living area, and 2 bathrooms. I couldn't tell you for sure the square footage, but the total house is 2700. Downstairs is larger than upstairs (dining, office, kitchen, main living, guest, utility, etc.).

Seems on ridge vent may be too close to the powered fan. So they have that left to remedy by removing that ridge vent, but can't get here again until Monday. That ridge is too small to do anything, in fact the roof overall doesn't have enough ridges for ridge vents alone.

Called the AC company out for today to check another time and am calling an insulation company as well.

Just for everyone's knowledge, it's seems like spraying the roof and sun facing walls at ~5:30 allows upstairs to start cooling off about 1.5 hours earlier than if you don't. Still miserable all afternoon, but temps are down by 9ish. Whereas when I wasn't able to do it yesterday, it was still hot come 9:30 outside of the room with the window unit.
